the ASR button on the dash is malfunctioning, what is its function
but when inside car I can push the master lock button and the doors want do anything. I hear a noise but nothing is happening
I checked the fuses and, in my owners manuel, it does not show a fuse for the horn!!
Cannot control the blower, it runs all the time and I need to pull the fuse when not driving. The blower also changes speed occasionaly. How much does the "final stage resistor cost?
When the car is moving fast it will just slow down wanting to. Hange fear and suddenly continue. As if it jerks. And also vibrate.
I have tried reconnecting and using key to lock and unlock doors and have tried unlocking and locking trunk. The alarm will not go off and allow me to start car.
First drive in the morning the car shakes as I drive for maybe about 5 min. Guessing it does that till the bad part warms up. After the initial 5 min the shaking goes away, but I feel a vibration coming through the seat. At 100 km/h it's at it's worst. Just dropped $3000.00 into new tires, struts, control arms, rear springs (broken) and an alignment at the dealer. At highway speed I dropped the car into neutral and coasted to a stop. The vibration never went away.
tranny shifts up and then shifts back even when stepping on itr
From under the hood
How do I know if this is a result of a bad fuse or bad fuses?
There's nothing come out when I put the A/C on, but I always see water come out underneath the blower motor.
no ac it blows hot air
the light only came on today.
I could use a diagram of the fuse/relay box located under the hood and the description of what size/type of fuse or relay is used for.Thanks in advance for anyone helping.
I just noticed this the other day. Had to jump car and noticed that the odometer stayed on even with the key off and out of car. Is there a relay of some type that tells the instrument panel(odometer) that the ignition is turned off. My battery is only 8 months old and test good.Could it be a bad cluster or some type of fuse or relay or could it be the ignition switch? HELP All the other lights turn off and is working properly.
